Sexy singer Erika Jayne is a jeans and T-shirt girl offstage

She is a blonde bombshell who has no problems with shaking her booty, gyrating seductively and chest-thrusting.

But US dance-pop singer Erika Jaynesaid she's not just a smouldering sex symbol.

"The Erika Jayne you see on stage is part of the performance. It's part of the fantasy I create and definitely part of who I am," said Jayne in a phone interview with M from Seoul, where she just completed a gig.

She declined to reveal her age.

"But when I'm not working, I'm completely different. I'm always in jeans and T-shirts, and I have my hair in a ponytail. I still try to wear a little make-up though."

Jayne, who has scored seven No. 1 hits on Billboard's dance chart - more than pop divas Katy Perry and Lady Gaga - also has a hobby that screams incongruity.

She is an avid collector of Hello Kitty toys and Barbie dolls. She said: "I've been a collector since I was a kid.

"That said, I don't collect every single toy or doll. Only the special ones, limited edition ones and those that appeal to me."

SOUTHERN BELLE

The Southern belle, who was born and raised in Atlanta, Georgia, is bringing her slew of catchy club jams such as Rollercoaster, Get It Tonight - a duet with US rapper Flo Rida, whom Jayne calls "a very humble, kind and sweet man" - and Painkillr to local partygoers as part of her ongoing Asian tour.

She will perform tonight at Altimate at 1-Altitude.

"Dance music has always been in my blood," said the entertainer, who runs independent music label Pretty Mess Records.

"Growing up, I did a lot of musical theatre. I also enjoyed clubbing and nightlife."

Her risque music video for Painkillr, released last month, raised eyebrows.

Shot entirely in black and white, it features Jayne cavorting in kinky tight lingerie and a few steamy scenes of girl-on-girl action.

"It is definitely my most racy piece of work," said Jayne. "The concept for Painkillr is sexy, and that's what the song requires. Sexy, racy, fun. Our visual image had to fit the lyrical content."

Sexy is what Jayne used to describe her concerts too.

"At my live shows, people go wild," she said.

"There's a lot of energy in the air, a lot of smiles. It's loud and sexy. "

Has she encountered over-enthusiastic male fans who get a little too touchy-feely?
